How to settings the routers

Router.map(function() {
  this.route('login', {path: '/'});
  this.route('signup');
  this.route('forgot-password');
  this.route('main'); 
});

I have the follow problem, when I use '/login' y I try manually to put /main this won't will redirect to me to '/login'

I wanna control the access because a I can navigate on all my templates if I write it into the search box
